Merck said it recently became aware of the decision and is reviewing its options.
John McDarby suffered a heart attack in 2004, and died of complications related to his heart problems in late 2007. He had been awarded $3 million for pain and suffering, and $1.5 million was awarded to his widow, Irma. The award also includes pre- and post-judgment interest.
McDarby was originally awarded $13.9 million. The portions of the award that were related to punitive damages, consumer fraud and attorney's fees were later overturned.
Merck took Vioxx off the market in September 2004 after a study showed the drug doubled the risk of heart attack or stroke. The company later agreed to pay $4.85 billion to resolve thousands of lawsuits. The McDarby case was one of a few that were excluded from that settlement.
The Whitehouse Station, N.J., company said it has won 11 of the 16 Vioxx-related cases that went to trial.
In afternoon trading, shares of Merck rose 4 cents to $32.07.
